Strip removal and relocation of follicular units (FUI) Follicular Unit Transplantation
This method represents a progression of the mini-/micrografting-technique.
To start with it is necessary to understand that hair grows in follicular units. A follicular unit is a natural grouping of hairs growing together in one single root.
See some follicular units via microscope:
As shown on the picture above you may notice lots of individual follicular units. Each unit has from 1 to 4 separate individual hairs.
During the extraction process a large piece of tissue is removed from the donor fringe by the use of a scalpel. The next step is to prepare the tissue for the transition into single follicular units (unlike mini / micro grafts) as seen below:
See some dissected follicular units:
A major difference between the mini-/micrografting-method and the FUT/FUI method will be seen in the natural outcome of a single follicular unit which needs no determined size to be relocated since it can be removed from the tissue in its particular size.
The aim of this method is to design a natural appearance with undetected hair transplant and seamlessly transitioning of the grafts. This cannot be achieved with the mini-micrografting-technique.
Positive aspects are:
- a large amount of grafts/follicular units can be extracted within one session
- less time consuming
- low pricing
- excellent growing yield
- higher density
- only little or even no shock-fallout *
- natural looking outcome
- no skin to be transplanted to the recipient site
Negative aspects of the strip-surgery are:
- a long scar remains visible for a lifetime period. Less freedom in personal hair styling as hairs cannot be cut shortly. The larger the scar the longer the patient´s hair has to be worn in order to cover it. The width of the scar often depends on individual predispositions and skin elasticity. The spectrum varies from 2 mm to + 1 cm.
- a longer healing time causes longer tension and pain at the backside of the head
- numerous grafts will be destroyed during the removal of the tissue
* Shock-fallout/shockloss: In case grafts or follicular units are placed in between remaining hair on the recipient site it is possible that some of the pre-existing hairs are going to fall out temporarily. These hairs will regularly grow back within the next 3 to 4 months.
